Have you had the problem with the battery wire connectors stretching so that they no longer fit tightly on the battery posts? Apparently it's a common problem even for a car such as the NSX. I've been dealing with it for a while. You can be driving along and the car just shuts down and then starts up again, or, you try to start the car and everything goes dark. I tried tightening the connectors, adding copper tape to the terminals but the problem would come back in a month or so. Went to CarQuest yesterday and got something called a battery post shim. It looks like a thimble made of lead and it fits over the battery post to make it slightly larger in diameter. The connectors now fit tightly. The part number is BP56C for those who are having similar problems. Or you can google "battery post shim" and you get lots of places where you can get them. Sure beats having to replace the connectors.
